Micro5 RTU

The MICRO 5 RTU is one of the latest in a long line of MICRO MOD RTUs designed for remote data acquisition and control applications. It incorporates advanced hardware and software techniques so you can implement your application in minimal time. Numerous hardware and software safeguards are incorporated into the design so you can be assured that the unit will continue to operate for many years in the most demanding field environment.

All MICRO 5s are optically isolated and come standard with 256K of battery backed RAM and 512K of program flash.

Operator Interface

  • The built-in operator interface (optional) uses familiar prompts
    and engineering units, eliminating operator guesswork and code memorization.
  • The 2×16 character local backlit display can scroll through
    several screens of information with a single key press.
  • For greater ease of use, the 20 line by 40 character backlit
    display can also be used with the MICRO 5, mounting up to 5
    feet away.
  • For greater ease of use, the LCD display
    can be mounted locally on the card cage or
    remotely up to 5 feet away.
  • Front mounted LED’s present digital I/O status and operating
  • Sealed tactile keyboard enables setpoint and mode changing.

Base I/O

  • I/O is optically isolated in groups.
  • I/O is modular and can be supplied with any combination of digital I/O, analog I/O and
    loop, or modem.
  • Digital I/O: Eight digital inputs counting 128 pps, pulse duration detection with 4 ms
    resolution. Four 10-amp relay outputs.
  • Analog I/O: Four 0 – 5V or 4 – 20mA analog inputs, 12-bit resolution. One 4 – 20mA, 12-
    bit resolution analog output (optional on analog board). 24V, 160mA loop supply.
  • Modem: One, RS232 port. 2-wire or 4-wire Radio/lease line connection OR 2-wire dialup
    telco jack.
  • Battery charger.


  • Two vacant expansion slots on the bottom of the MICRO 5 accept any MICRO 9
    expansion boards.
  • Module design enables easy customization with choices of modem, serial ports, printer
    port, dialer, loop supply, optically isolated I/O, compact flash, etc…

I/O Connections

  • Individual screw terminals using rising cage clamp design are capable of accepting 14 AWG
  • Screw terminals plug into PC board headers. MICRO 5 can be “unwired” without removing field
    wires individually.


  • BSAP


  • Option of enclosure with or without local display – back panel mount.
  • Panel mount enclosure with front flange, local display and keypad, and star nuts for
  • All enclosures have front status LED’s
  • All enclosures are made of 16-gauge powder-coated steel.


  • The MICRO 5 is programmed via our support software.
  • The MICRO 5 support software has over 190 pre-programmed modules.
  • MICRO 5s can also be programmed using BASIC and ladder logic.
  • Operating system is field upgradable.
